Hi,
the highest power/torque will be achieved with a parallel combination. It will also be the combination which gets hottest fastest.
The trick to wiring them in parallel is to ensure that the two windings of the pair are co-phase. You either have to measure it by feeding a signal into one
coil and monitor the phase of the voltage induced in the second.
The diagram you posted suggests that you have enough information to do it by trial and error if the groupings of the four windings into two phases can be believed.
Wire the two phases in what you think is co-phase and try it. The swap the one winding in one phase only and try it, if its better then that phase has now got co-phase windings,
if not they were co-phase in the previous wiring condition. Now do the same excerise with the other motor phase.
Once you've got it correct don't keep fiddling with it. It will just keep introducing more diagnostic variables when you are actually trying to eliminate them.

Once I get it right, I'm done fiddling. LOL
I know which coils pair. I'm not worried about that. I verified it earlier as well.
To find the polarity of the paired coils, I excited one of the coils to see the step. I kept trying different combinations of polarities and coils until it did NOT step from the known step.
Once I had that pair set with the proper polarity I was able to do the same with the other set of coils.
When I was done I compared to the diagram I posted and they match. Basically, I double checked them.
Now I have them wired in parallel and just need to find a way to make them step clean.
